摘要： This invention provides a method for rolling an external pipe thread, a rolling head and device thereof. A rolling wheel carries out a thread rolling, wherein the thread rolling starts from a thread tail of the external pipe thread and moves towards a thread head of the external pipe thread, thereby completing the thread rolling. The rolling head of the invention comprises at least one rolling wheel arranged along a circumference, a corresponding rolling wheel axle and a corresponding rolling wheel seat; the rolling wheel is rotatably fixed to the rolling wheel seat via the rolling wheel axle; and the rolling wheel is provided with a pipe thread forming part having a thread length less than an effective thread length of the external pipe thread to be rolled. The rolling head of the invention also comprises a radial regulating device that can realize dynamic rolling and real-time whole-process regulation of radial position of the rolling wheel for the purpose of forming the taper as required by rolling process. The invention also provides rolling device including aforesaid rolling head. Solutions as provided by this invention are expected to guard against deformation to the pipe end during rolling, significantly save materials for hollowed cylindrical blank, and improve the rate of finished products.
